Need help in setting up SDDC Management Pack to discover vCenter Server services. Using MP of version 6.0. Have set the credentials as well but the services have not been discovered yet. Please help in this.

Have already completed both the configurations, permissions and the credentials for VC SDDC object, but unfortunately it still does not discovers the services. Even re-verified the permissions by logging to VC using the earlier supplied credentials, was able to see the services tab which confirms that the permissions have been propagated but it vROPs they are not getting discovered.
